At 112 years, Japanese supercentenarian Masazo Nonaka has just been recognised as the world's oldest man.

The new record holder was born on July 25, 1905 – the same year Teddy Roosevelt was inaugurated as the 26th president of the US. The first radio broadcast happened in 1906.

Also, cars looked like this, which is amazing: 


The 112-year-old lives with his family, who manage a hot springs inn in Hokkaido.

"He needs a wheelchair to move but he is in good condition," Yuko Nonaka, his granddaughter, told AFP.

"He loves eating any kinds of sweets - Japanese or western style."

"He reads newspapers everyday and often soaks in the hot springs," she added.

That sounds like a pretty amazing way to live out your centennial teens, and that gummy smile pulls at our heart strings.

Even though Nonaka's longevity is an amazing feat, there are several people alive today who are even older - but all of them are women. The honour of the oldest living human goes to another Japanese person - Nabi Tajima, who is 117 years old.

When it comes to the science behind longevity, we're still not sure what makes some people live such long lives. But it's a pretty safe bet that none of these supercentenarians are likely to have been injecting the blood of teenagers to try and stay young.

But with an anti-ageing gene discovered in an Amish family, and scientists finally being able to reverse DNA ageing in mice, we might be closer than you think to slightly longer, and hopefully healthier lives. 

That being said, maybe don't stop going to the gym just yet.
